3-D light brings the recording density to 0.5 TB / square inch

InPhase (USA) has announced a much higher data density than any other storage technology on the market so far. The record number that the company has successfully recorded is 515 GB of data per square inch.

Holography technology can be multiplied by storage capacity because it takes advantage of 3-dimensional volume efficiency instead of just writing data to the surface of the material. The density recorded in this technology is achieved by completely different factors than magnetic storage technology. The density here depends on the number of pixels / bit in a data page, the number of pages stored on a specific container, the flexibility of the recording material, the thickness of the material and the wavelength of the recorded laser.

Illustrating the process of recording data in 3-dimensional light of InPhase.

In InPhase's experiment, the result was more than 1.3 million bits / page of data and 320 pages of data 0.067 degrees apart, stored in the same volume of material. A collection of such data pages called by InPhase is a 'book' and its PolyTopic-named architecture allows multiple three-dimensional data to be stored in the same volume of material by overlapping Not just the pages but the 'books'.

Three overlapping 'books' overlap are recorded with a slot of 700 micrometers (1 micron = 1 millionth of a meter). The material that InPhase uses is called Tapestry, which is 1.5 mm thick with a laser wavelength of 407 nanometers.

InPhase expects to ship drives and software using 3D light technology this year. The first drive generation will have a capacity of 300 GB on a single disk with a data transfer rate of 20 Mbps. Next will be the introduction of a product line with storage capacity from 800 GB to 1.6 TB (terabyte - each TB equals 1,000 GB).

" The IT community is witnessing extraordinary progress in data storage capabilities ," said Wolfgang Schlichting, research director for mobile storage for IDC Research Group. ' The new achievement of InPhase is an important milestone in the technology to increase the density of information storage, while also showing a tremendous increase in storage capacity thanks to 3-dimensional lighting technology. This will also be another potential option to add to existing technologies in the storage sector . '
